Mr Turner trailer: Timothy Spall in Mike Leigh's Cannes-bound biopic

Mike Leigh's new film Mr Turner has unveiled its first trailer ahead of its Cannes Film Festival debut.

The biopic stars Timothy Spall as JMW Turner, a British painter famed for his landscape work in watercolours. He was dubbed "the painter of light" and it's thought his final words were "the sun is God".

Leigh's film will premiere at Cannes this evening (May 15) and marks his first time back at the festival since 2010's Another Year.

He won the event's prestigious Palme d'Or award in 1996 for Secrets & Lies.

Mr Turner will open in the UK on October 31 and features Lesley Manville, Marion Bailey, Dorothy Atkinson and Paul Jesson in the supporting cast.
